Application filed June 21, 1913. Serial No. 775,005:

To all whom it may concern Be it known that I, CLARENCE L. BROW'ER, acitizen of the United-States, residing at Chrome, in the county ofMiddlesex and State of New Jersey, have invented certain new and usefulImprovements in ldosh- Cranes, of which the following is aspecification.

Among the objects of this invention is to provide an eilicient de 'cefor conveying the anodes from the mold or conveyor to the boshes, ,andfor providing means of adpistment between the grappling device and theup the anode and where it will deposit the same.

The various features of novelty and advantage will be brought out moreparticularly in describing the invention in connection with the drawingsand diagrams ac companying this specification, In the drawings, onepracticable embod ment of the invention is illustrated, in whichdrawings-v E Figure l is a plan view of various portions of the plantshowing the invention in connection therewith. In this view there isillustrated the furnace, the conveyer, the crane, and a plurality ofboshes. a cross-section of the parts illustrated in Fig. 1 taken atabout the plane of the line 2-2 in Fig. 1. Fig. 3 is an end elevation ofa ortion of the trolley, and a cross-section of the trolley bridge, andshows a broken away portion of an anode carried by the crane; Fig. i isa side elevation of the trolley and the crane carried thereby; and Fig.

5 is a top plan view of the trolley.

In one method of refining copper, the copper is run in a moltencondition from some suitable furnace-a furnace is illustrated herein at10-into molds for molding the anodes. The molds are illustrated in acontinuous rotary conveyer. There is shown a wheel 11 having a series ofmolds 12 carried thereby into which the molten copper is run and isformed into anodes 13. This conveyor is shown located between thefurnace 10 and a lurality of boshesin which the'anodes will be quenchedbefore being conveyed to the electrolytic bath.

The boshes are represented at 14,- 15 and 16; the bosh 15 is shown atone side of the conveyor substantially diametrically opposite thedischarge spout 17 of the furnace.

The conveyor will be rotated step by step,

' the anode.

Fig. 2 is each of the molds 12 will have a sufiicient quantity of metalrun into it, and the conveyer will then he stepped around to bring thenext mold in position. When thein'old e ed anodes arrive in the regionof the bosh into which they are to be placed, they wi ll be removed fromtheir molds and cen'veyed to and deposited in the bosh Each of the moldsis provided with some suitable means for clearing the cast anode. In thepresent instance a pin 18 passes upwardly throu h the bottom of themold, and

has an end epending below the mold in position to'be engaged by a camsurface. 19 adjacent the position where the anode will be removed fromthe mold. The pin will be caused to rise and thus lift the end of Theouter end of the anode is shown provided with a pair of engaging lugs20.

It is found difiicult in practice to always have the molds from whichthe anodes are to be taken brought to a given working point at the timethe crane is ready to act. The crane must be able to do its work atvarious positions along the path of revolution of the molds. For thisreason in engaging the anode, moving it and depositing it in position, acertain amount of flexibility of movement must be provided in theengaging device, and owing to the location and arrangementof the partsthe engaging device must move positively to its position to engage theanode, and must become positively positioned before depositing the samein the quenching bath. The invention therefore provides a crane having agrapping device or pick-u with aswivel motion allowing rapid adJuStmentto be made to ac: commodate the difference in position be:

tween the mold and the bosh that it is desired to cover. As shown in thedrawing, the boshes are placed side by side, whic naturally will bringthem indifferent positions along the path of revolution of the mold. Theboshes are provided with racks in the ompa n ashes This present e otherreason tor providing the flexibility of movement of the grapple orpickup.

In the illustration there is shown a bridge 22 havin wheels 23 runningupon tracks 24.

The bridge is provided with rails 25 for receiving the wheels 26 of thetrolley 27.

' -Suitable' means will be provided for causing versely of the other, sothat it may be moved by the resultantof a compound movement Themechanismfor engaging the anodes will move transversely of the plane of thiscompound movement, and will also have a swiveling motion in a planeparallel with such plane of movement.

There is shown mounted upon the trolley a rigid leg, that is rigid inthat it is held with the trolley for movement in its two movements, andwill be practically free from vibration or swinging independently of thecarrier or trolley. This leg in the present illustration comprises atubular shaft 30 which is caused to rotate by means of a feather 31engaging a guide 32 (presently to be described), and throughwhich guideit is caused to travel. The traverse of the member 30 is effected 'by acable 33 connected to the head 34. .The cable runs over a pair of drums35 provided with cable grooves 36. The grooves are shown right and lefthandc'd so that the head 34: will not be moved from side to side as thecable is wound and unwound. The head 3 is shown as having a swivelconnectio riewith the shaft 30 and is guided in its traverse and heldfrom rotation with the shaft 30 by means of a iair of guide rods 37passing through gui es 38. The guide rods 37 are movable vertically withthe shaft 30. Each end of the head is shown provided with a sheave 39over which the cable 33 passes for permitting the cable to automaticallyadjust itself should there be more stretch upon one'side than upon theother. A too free movement of the cable however is prevented by suitableclamps 40, or frictiondevices. The rigid leg 30 is controlled in itsvertical traverse and supported by a cable and an outrigger .con-

' struction. v

The grappling device 41 is shown nonrOtatably carried by the shaft 30and rotaa motor 46 mounted upon the trolley. various motors foractuating the varmus parts ot the apparatus will have their con trollingdevices conveniently located for th e manipulation of "the operatorwhile or the 7 platform 29.

tions 121 122 and 123 in which osilions .I. l w l V the anodes arelirted by the pins 18. h roni either of their positions the crane maycarry the anodes to either of the boshes 142, 15 or 16. T9 do this thebridge 22 will be moved upon the tracks 24- to a [H'iSlilOl'l in. linewith the anode to be lifted, and the trolley will be .moved' over theanode into such a position that by a swivelirg the head 41 (ifnecessary) and a rl wnward traverse of the head and shaft 30, Lne hooks42 will come into position to engl'agr the lugs 20 which have beenraised from the mold by means-0f pin 18 and cam 19. The head will thenbe raised to clear the anode 13 from its mold. The trolley'will then begiven the proper movement by means of its traverse of the bridge, andthe bridge of its tracks, to bring the center of the shaft 30 into linewith the longitudinal center of the bosh.

During this movement the head ll will be caused to rotate by means ofthe worm gearing above referred to, and when the anode 13 has beenbrought to its proper position relatively to a pair of the notches 2Lshaft 30 and connected mechanism will be caused to lower by means of theplaying out of the cable 33, and the anode no; asited in the bosh. Whenthe anodes are taken the from the position indicated at 122, no swivcling of thehcad will be required; but when taken from positions 1.21and 123 the heal will be swiveled in opposite directions to bring thehooks into proper engagement with the ears on the anode castings. it maysometimes arise that some diiiiculty will be experienced in conveying ordepositing an anode where desired, and that the revolution. of the moldswill have brought the anode past its usual point of being taken up, inwhich case the operator will be able to readily move the grapple intoits proper posi tion for engaging the anode and for conveying it anddepositing it where desired. The extensible part of the crane is thusseen to be rigid and to be positively moved from one position to anotherand positively held in such position and the swivclii mo tion of theengaging portion of this tensible member is also positively moved andpositively held in position.

It will be apparent that the form of the device herein shown anddescribed is illustrative of the invention, and that changes may be madeWithin the scope of the claims without departing from the-spirit of theinvention, for the purpose of adapting the im vention to the exigenciesof its use, and that it may be used in other situations than thatdescribed, the present showing being one of its many uses.

Having described my invention, I claim:- 1. The combination with a cranetrolley, and means for imparting to the same the resultant ofa compoundmovement in a'substantia-lly horizontal plane, of a horizontallydisposed head, a vertically disposed guide rod carried by each end. ofsuch the trolley, a rigid shaft carried by the central portion of thehead, means for rotating the said shaft, a grapple rotatable with thesaid shaft, and means for raising and lowering the head relatively tothe trolley.
